I have a B-Square that I've used for years. It's stout enough to use for sizing brass with L.E. Wilson f/l sizing dies.

Dale Carpenter manufactures this hydro base, all hydraulics are contained in the base itself. You have to add the arbor press, in this case, a K&M unit. Other arbor presses such as a Sinclair will fit just fine.

I like that, may I ask how the sensitivity is on it ? - Does it easily show the difference in force required to seat bullets where neck-turned brass is used and all pieces of brass were sized with the same bushing size ?

It obviously will not show tiny differences but will show differences. As with the other hydro type presses, seating is done slowly to feel differences and see differences on the gauge. I use powdered moly to coat the inside of the neck and bullet before seating which help make seating slick.

Look at the 21st Century Arbor Press options here :
http://www.xxicsi.com/new-generation-arbor-press.html
or
http://www.xxicsi.com/arbor-press.html

The new generation has the longer handle and the option of the loading block. You can order direct from 21st Century.
These all good choices and you will be very happy with any of them.

OR...you could just upgrade now and go with the Hydro press

Thanks

Pete

love ya Pete hope things are going good for you its been awhile.

After having and using a direct hydraulic measuring and an indirect Belleville washer stack measuring press I have come to the conclusion that a sensitive hand using a properly set up press can be as effective as using measured forces. I find that I can develop a sense for lighter and heavier seating forces as well as obvious 'way out of range...going to be a fouler' seating forces and segregate the cases into groups to be used in a particular match. I don't even look at the dial on my gauge very often gauge anymore.

IME it does....annealing is also part of the bullet seating “tension” consistenty. The biggest change to my bullet seating consistence was to add a few K&M expander mandrels in + .0005 dia to my final brass prep prior to lube and seating.

Thank You Ben,

I appreciate your feedback and I fully agree that annealing plays a big role in consistency of tension and the seating process. - As well, I'm dipping my bullets in a Moly compound to apply a very light "dusting" to each just prior to seating the bullet. - And I like the idea of the custom sized K&M expander mandrels also to keep the inner part of the neck as round as possible, even using neck-turned brass.
- Outstanding feedback which is appreciated !!

Regards, R

I like the initiative behind these seating force devices.
But that measure is too late, as you're seating a bullet to get it, and can do nothing about it by then.

A different approach is to measure pre-seating forces.
Here you can adjust each round to match -prior to seating actual bullets.
This can be handled with an expander mandrel pressing against a load cell.
Then you would seat bullets into matching necks with an inexpensive arbor press.

Ideally we would have a tool to directly measure hoop tension through expansion forces within springback range.
But it seems none exist, and I haven't developed one yet.

Do you have a video of this device in action? Will you be offering these? Looks like a very cool alternative to a hydro press, and possibly a more accurate measurement.

The hart is the finest non-hydro press out there. I use a k&m myself just because that was my first one and its the one ive kept since i dont use inline seating dies anymore. I have it and the 21st hydro

I have parts to build one too, but I plan to use a stepper motor to pull on the handle to remove me as a variable.

For years reloaders have been claiming tension is the way to go, I claimed I had tension gages, I claimed all of them were calibrated to pounds, I claimed there was no conversion from tension to pounds and now reloaders have the opportunity to purchase a machine that measures force in pounds, and now? You claim that will not work?

And still the reloader has no way to measure tension. I have gages that measure deflection in thousandths with a conversion to pounds.

All I suggested in my last post is that pre-seating forces can be considered -before actual bullet seating.
As to any forces(any at all) holding toward a standard in neck tension, that isn't going to happen until someone makes it happen. Different approach.

if you dont pull it and cant feel it you may as well use a rubber mallet

Tension is the direction of a force that is pulling material apart.
Compression is a force that is pressing material together.
You should try reading a text in the most basic engineering mechanics course called statics. Statics is all about understanding tensile forces (aka tension) and compressive forces. I bet you could understand it if you worked real hard.
Otherwise you can remain as you are...

Hes the only one that understands and wont let us in on the info

Did you find a better way?

I prefer to use newlon micrometer dies i ream myself.
